SPECIFICATION forming part of Letters Patent No. 621,235, dated March 14, 1899.

Application filedl October 21, 1895. Serial No; 566,364'. (No model.) i l T0 all whom it may concern: A

Be it known that we, JOSHUA VALENTINE Evns, WILLIAM DANIEL OBRIEN, and LOUIS FREDERICK OBRIEN, subjects of the Queen of Great Britain, and residents of Belfast, in the 1895, and in Germany, No. 86,783, of November 1, 1895,) of which the following is a specilication.

This invention relates to sad-irons, the objects being to produce an iron of this character which will be freely movable as usual, which may be heated by gas continuously from within, and from which the foul air and gases due to the combustion of the heatingiiame may be positively exhausted and removed without injuriously affecting the heating-flame.

With these ends in view our invention consists, essentially, of a sad-iron having an internal combustion-chamber provided with a burner, means for supplying gas to the same, an internal exhaust-chamber, a partition between said chambers provided with an opening through which they communicate, and means for exhausting the products of combustion from said exhaust-chamber.

The invention further consists in the details of construction and combination of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is an elevation of a smoothing-table, showing the connection of the irons with the gas and air supply pipe and the lexhaust for the foul gases and products of combustion. Fig. 2 is a side elevation of one of the said irons. Fig. 3 is a vertical longitudinal section through the same. Fig. t is a top plan view, the handle being removed. Fig. 5 is a horizontal longitudinal section of the same.

Referring to the drawings, A indicates the combustion-chamber, formed in the interior of the iron and extending longitudinally of the same throughout substantially its entire length. a is an exhaust-chamber also formed in theA interior of the iron and extending transversely of the same at its rear end and in rear of the combustion -ch'alnber- The exhaust and combustion chambers are separated by means of a verticalpartition a', situated betweenthem and provided at or near its top with an opening a2, through which they communicate for the purpose hereinafter stated. Otherwise these chambers are entirely closed againstA communication with each other or with the exterior of the iron, except through the mediu'm of pipes Gand E and aperture j, a's hereinafter described.

B is a burner perforated on its under side at intervals throughout its length. This burner enters the combustion-chamber at or near its rear end through the side wall of the iron (into which it is screwed) and extends longitudinally of the said chamber, whereby heat is applied directly to the sole of the iron substantially throughout its entire length. The end of burner B projects laterally to the outside of the iron a suitable distance and has connected to it one end of a flexible pipe E, which connects at its opposite end with a suitable gas and air supply pipe or main G for supplying gas and air to the burner. The

products of combustion which are generated.

in the chamber A pass through aperture a2 into chamber ct,from which theyare exhausted at its other end seated beneath a Vertical stud projecting from the upper face of the iron and which enters a suitable slot formed in said plate. The plate is adapted to be swung aside when access to the interior of the iron is desired.

K is a shield located beneath the handle of the iron to protect the hand of the operator from the heatradiated from the iron.

L is an aperture in the side wall of the iron, closed with mica or other transparent material, through which the iame may be viewed.

From the above itwill be seen that we produce a sad-iron freely movable for all practical purposes, one from which there will be no escape of foul or deleterious air or gases into the apartment in which it is operated, and one from which the products of combustion are thoroughly and positively exhausted; but the gist of our invention resides in providing the iron with two distinct chambers, one in which the heating-flame is located and in which the combustion of the air and gases is effected and the other to which the products of combustion escape and from which they are exhausted, whereby the efficiency of the heating-name, owing to its situation in a compartment other than that from which the exhausting operation is performed, will not be detracted from or be in any manner injuriously affected.

It is to be understood that in attaining the' ends in view we do not limit or confine ourselves to the details herein set forth and that various changes such as would suggest themselves to the skilled mechanic for the better accomplishment of these ends may be made without departing from the spirit or scope of our invention.

Ilavin g thus described our invention, what we claim is l. In a sad-iron, the combination with an internal combustion-chamber provided with a burner, of means for supplying gas to the same, an internal exhaust-chamber, a partition between said chambers provided with an opening through which they communicate, and means for exhausting the products of combustion from said exhaust-chan'iber, sub'- stantially as described.

2. The combination with a fixed gas-supply pipe or main, of a portable, freely-movable sad-iron provided with an internal combus'- tion-chamber, an internal exhaust-chamber,

a partition between said chambers provided Awith an openingthrough which they communicate, a iexible pipe connected at one end with the gas-supply main and at its otherend with the internal combustion-chamber, to supply gas to the iron, a second Ilexible pipe connected at one end with the internal exhaust-chamber, and an exhaust apparatus connected with the other end of. said pipe for exhausting the products of combustion, substantially as described.

3. In a sad-iron, the combination with an internal longitudinal combustionehamber,of a burner entering the side wall of said chamber and extending forward longitudinally of the same, means for supplying gas to thev
